Barcelona's technical director Txiki Begiristain (L) and football coach of Barcelona Josep Guardiola (R) talk during a press conference to explain the dispute over Lionel Messi and his participation in the Olympic Games in China on August 7, 2008 in Barcelona. Messi scored one goal and set up another as reigning Olympic football champions Argentina began the defence of their title with a 2-1 win over the Ivory Coast in Shanghai after a ruling from the Court of Arbitration for Sport threatened the Barcelona star's participation.
